Abstract

The basidiomycete fungus, Chondrostereum purpureum Fr. Pouzar, has been found to be a good potential bioherbicide candidate for control of hardwood vegetation in forests. However, its interaction with some agrochemicals that are normally employed in forest protection was not known. Employing two concentrations (0.01% v/v and 0.1% v/v) of several agrochemicals, a laboratory study was conducted to assess their impacts on the infective mycelia. Except for Bond, and Suntan gel-2, most adjuvants, sunscreen agents and pesticides (herbicides, fungicides and insecticides) were fungitoxic at 0.1%. Fungitoxicity was concentration dependent and the results indicate that the possibility of tank-mixing the basidiomycete with agrochemicals appears limited and the possibility of agrochemical residue effects on survival of the basidiomycete is implied. Nomenclature: Bond, aliphatic oxyalkylated alcohol + synthetic latex; Suntan gel-2, ethyl-hexyl-p-methoxycinnamate.
